[VenetaBogoeva]

1. Add new custom package (NewPackage)
2. In Page templates backend create pure mvc template with the following name NewPackage.Test (without Developer name)
3. Add a .cshtml file in the File Structure under ~\ResourcePackages\NewPackage\MVC\Views\Layouts folder with the same name as the template from point 1 ("Test")
4. Navigate to the backend and verify if the template is based to the layout file

Actual result is:

The template is not based on the layout file
